Representational level matters for tone-word recognition: Evidence from form priming.

Area of Science:

• Psycholinguistics
• Phonetics
• Cognitive Science

Background:

• Spoken-word recognition involves accessing stored lexical information.
• The role of lexical tone in Mandarin spoken-word recognition is not fully understood.
• Investigating the representational structure of lexical tone is crucial for models of word recognition.

Purpose of the Study:

• To investigate the impact of lexical tone representation on spoken-word recognition in Mandarin.
• To determine how different types of primes (real words, pseudowords) influence the recognition of tonal words.
• To explore the processing of segmental and tonal information during word recognition.

Main Methods:

• A form priming experiment using a lexical decision task was conducted.
• Participants responded to monosyllabic Mandarin target words preceded by five types of primes.
• Primes varied in their relationship to the target word in terms of segmental form and lexical tone.

Main Results:

• Facilitation was observed when target words were primed by pseudowords sharing the segmental syllable but differing in tone.
• No significant form priming effect was found for target words primed by real words with only tone contrasts.
• Distinct priming patterns emerged between real-word and pseudoword primes.

Conclusions:

• The recognition of Mandarin tonal words is influenced by the representational level of tone accessed by prime words.
• Findings support connectionist models positing a hierarchical representation of lexical tone.
• The interaction between segmental and tonal information processing is key to understanding Mandarin word recognition.
